I’ve had a sensor up outside for about a year after which it stopped reporting. The red power light comes on, but when unplugging and restarting at a different location apart from the wi-fi network it was formerly on, I never get the startup PurpleAir-\*\*\*\* network to appear. My assumption is that the wifi for the sensor has stopped working altogether and I will need to replace the sensor. Just checking to make sure there is nothing else I can try to troubleshoot or fix the issue with the sensor not reporting or able to connect. Thanks

Hi @jcothran, make sure that you leave the device plugged in away from the previous network for at least 10 minutes when looking for the PurpleAir-\*\*\*\* WiFi network.

If that doesn’t work you can try [erasing the device’s flash memory and re-flashing the firmware](https://community.purpleair.com/t/the-purpleair-utility/673). Send an email to [contact@purpleair.com](mailto:contact@purpleair.com) if re-flashing doesn’t work or you would like assistance with the process.

Thanks Joshua! Flashing the device worked to get the wi-fi and connectivity going again.
